Bloomberg News Hypes Non-Peer-Reviewed Climate Study

A Bloomberg News article claims that new data from Norway "Shows" that global warming is "Less Severe Than Feared." But Bloomberg failed to mention that this claim is based on a PhD thesis that has not yet been peer-reviewed or accepted for publication by any scientific journal.

A press release by the Research Council of Norway states that new research has found that the amount that earth's temperature will rise if we continue emitting greenhouse gases at our current rate will be lower than estimates from the United Nations' Intergovernmental Panel on Climate Change (IPCC). The IPCC, a group that assembles thousands of experts to review and summarize predominantly peer-reviewed research on climate change, estimates that doubling the amount of carbon dioxide in the atmosphere would cause warming between 2°C and 4.5°C (3.6° to 8.1° F), and estimates that 3°C (5.4° F) is the most likely outcome. By contrast, the Norwegian study estimates that 1.9°C (3.4° F) is the likely outcome.

But the research, which runs counter to the IPCC and the extensive body of research on this topic, is actually a PhD thesis. It has not been accepted by a scientific journal and thus should be treated as preliminary. And according to environmental scientist Dana Nuccitellli, writing at the climate science website Skeptical Science, the study may be flawed, by "overfitting the short-term natural variability" in temperatures.

But Bloomberg did not mention that the research was not peer-reviewed in an article that is now predictably being hyped by right-wing media seeking to downplay the impacts of global warming.
